Medchemexpress LLC Lipopolysaccharides, from E. coli O55:B5 (LPS) | 93572-42-0 | MFCD00164401 | 100 MG
Lipopolysaccharides, from E. coli O55:B5 (LPS, from Escherichia coli (O55:B5)) are endotoxins and TLR4 activators extracted from Escherichia coli (E. coli O55:B5) and are classified as S (smooth) type LPS. They possess the typical three-part structure: O-antigen, core oligosaccharide, and lipid A. Lipopolysaccharides, from E. coli O55:B5 activate TLR-4 in immune cells, exhibit high pyrogenicity, and demonstrate dose and serotype specificity. They can be widely used to induce cellular inflammation and establish animal models related to inflammation.

Medchemexpress LLC SN-38 glucuronide | 121080-63-5 | 99.49% | 568.53 | 50 MG
SN-38 glucuronide is an inactive metabolite of the anticancer active molecule Irinotecan and has toxic effects on the gastrointestinal tract. Irinotecan is a topoisomerase I inhibitor used for researching colon and rectal cancer. SN38-G is the glucuronidated metabolite of SN38. Cells with the ability to metabolize SN38 to SN38-G are more resistant to extracellular SN38 than cells lacking this capability. SN-38 glucuronide can also serve as a substrate for gut microbial β-glucuronidase enzymes, which remove the glucuronic acid moiety to reactivate SN-38, thereby increasing its toxic effects on the gut.
